IDCHIP · Operational Amplifier · SOIC-8
LM258 from IDCHIP, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Output of op-amp channel 1. Can source ~40 mA and sink ~15 mA at VCC=15V. |
| 2 | 1IN- | input | Inverting input of op-amp channel 1. Input bias current typ ±45 nA, max ±150 nA at VCM=0V. |
| 3 | 1IN+ | input | Non-inverting input of op-amp channel 1. Common-mode input voltage range 0 V to VCC-1.5 V. |
| 4 | GND | power_in | Ground / negative supply (VEE). Connect to 0 V for single-supply operation or to negative rail for dual-supply operation (down to -16 V). |
| 5 | 2IN+ | input | Non-inverting input of op-amp channel 2. Common-mode input voltage range 0 V to VCC-1.5 V. |
| 6 | 2IN- | input | Inverting input of op-amp channel 2. Input bias current typ ±45 nA, max ±150 nA at VCM=0V. |
| 7 | 2OUT | output | Output of op-amp channel 2. Can source ~40 mA and sink ~15 mA at VCC=15V. |
| 8 | VCC | power_in | Positive supply voltage. Absolute max 32 V (single supply) or ±16 V (split supply). Typical quiescent supply current 0.5 mA at VCC=5V, 1 mA at VCC=30V. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|

122 KB | You want the bare part, or you mark your own boards. |

1.4 MB | You want the part with LM258 already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 336 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
